Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery before working on electrical systems.

2. Addressing Check Engine Light

Sub-steps:
1. Use the OBD-II scanner to retrieve trouble codes.
2. Refer to the service manual for troubleshooting specific codes.
3. Repair or replace faulty components as indicated by the codes (e.g., replace faulty sensors or clear vacuum leaks).

3. Resolving ABS and Traction Control Lights

Sub-steps:
1. Inspect ABS wheel speed sensors for damage or disconnection.
2. Check the ABS fuse and replace if blown.
3. Test the ABS module with a scanner for fault codes and repair as needed.

4. Fixing Battery Warning Light

Sub-steps:
1. Clean battery terminals and ensure they are tightly connected.
2. Test the battery's voltage (should be around 12.6 volts) and replace if below specifications.
3. Check the alternator by measuring voltage output while the engine is running (should be 13.8-14.4 volts).

5. Addressing Oil Pressure Warning Light

Sub-steps:
1. Check the oil level using the dipstick; top up if low.
2. Inspect for oil leaks under the vehicle.
3. If oil level is adequate, replace the oil pressure sensor if faulty.
